Summary & Overview
CPT 68362: Conjunctival Flap (Free) Creation
CPT code 68362 documents the surgical creation of a free conjunctival flap used to cover defects on the ocular surface. This procedure is significant for ophthalmic surgeons and payers because it addresses complex ocular surface wounds and reconstructions that can impact visual outcomes and downstream care utilization. Nationally, accurate coding of conjunctival grafting supports appropriate claims processing and clinical registries for ophthalmic reconstructive procedures.
Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service, and which payers commonly reimburse for ophthalmic surgical services. The publication summarizes benchmark considerations, coding guidance context, and policy updates relevant to CPT code 68362, while also noting areas where input data are not available. Intended audiences include billing managers, ophthalmic surgeons, practice administrators, and policy analysts seeking a clear national overview of this reconstructive ocular procedure and its billing implications.
Billing Code Overview
CPT code 68362 describes the creation of a conjunctival flap, a flap of free conjunctival tissue (the tissue that covers the inside of the eyelids and the eyeball) used to cover another site. This procedure is an ocular reconstructive/plastic surgery technique performed to provide tissue coverage for defects or wounds on the ocular surface.
-
Service type: Surgical — conjunctival graft/flap creation
-
Typical site of service: Operative setting such as an outpatient ambulatory surgery center or hospital operating room where ophthalmic surgical procedures are performed.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient presents to an ophthalmology clinic with progressive conjunctival scarring and a localized conjunctival defect following excision of an ocular surface tumor. The surgeon plans a conjunctival autograft: creating a flap of free conjunctival tissue to cover the defect and restore ocular surface integrity. The procedure is performed in an outpatient ophthalmic surgical suite under monitored anesthesia care or local anesthesia with sedation. Preoperative steps include informed consent, antiseptic prep, topical anesthetic, and marking the donor site. Intraoperative workflow includes harvesting a free conjunctival flap, securing the graft to the recipient bed with fine absorbable sutures or fibrin glue, ensuring graft orientation, and placing a protective patch or shield. Postoperative care includes topical antibiotics and steroids, patch removal instructions, short-term follow-up within 24–72 hours for graft check, and subsequent visits to monitor healing and visual function. Typical payors include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work, time, or complexity substantially exceeds typical for 68362 (attach supporting documentation). |
23 | Unusual anesthesia | Use when general anesthesia is medically necessary for this ophthalmic procedure instead of local/regional. |
26 | Professional component | Use when billing only the physician professional component separated from technical facility services. |
50 | Bilateral procedure | Use when identical conjunctival graft procedures are performed on both eyes during the same operative session. |
51 | Multiple procedures | Use when 68362 is performed in the same session with other distinct surgical procedures (list primary and apply modifier to additional). |
52 | Reduced services | Use when the procedure is partially reduced or not completed as planned. |
54 | Surgical care only | Use when billing only for the intraoperative surgical portion and another provider bills pre/postoperative care. |
55 | Postoperative management only | Use when another provider billed the surgical portion and you bill for postoperative care. |
58 | Staged or related procedure or service by the same physician during the postoperative period | Use when 68362 is planned as a staged reconstructive procedure following an initial operation. |
78 | Return to operating room for related procedure during the postoperative period | Use when a related reoperation is required during the global period. |
59 | Distinct procedural service (Note: not in raw list but standard; omitted per input restrictions) | Data not available in the input. |
